The table shows the thermodynamic data for a reaction. thermodynamic data energy of the reactants energy of the products activation energy 160 kj 370 kj 260 kj which of the following statements explains if the reaction is endothermic or exothermic? the activation energy is lower than the change in enthalpy, so it is an exothermic reaction. the activation energy is higher than the change in enthalpy, so it is an endothermic reaction. the change in enthalpy is −210 kj, so it is an exothermic reaction. the change in enthalpy is +210 kj, so it is an endothermic reaction.

The change in enthalpy is +210 kJ, so it is an endothermic reaction.

Explanation:

The change in enthalpy = The energy of products - the energy of reactants.

For this reaction: The change in enthalpy = The energy of products - the energy of reactants = 370 kJ - 160 kJ = + 210 kJ.

So, the right choice is: The change in enthalpy is +210 kJ, so it is an endothermic reaction.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
